  • Method for preserving enzyme
    Patent number: 9353348
    Abstract: The problem is to provide a method for inexpensively and simply preserving an enzyme of a microbial biomass obtained by culturing and improve the enzyme activity during preservation. Provided is a method for preserving nitrile hydratase, characterized in that microbes having nitrile hydratase activity are cultured while being protected from light, and the resulting biomass is crushed using a high-pressure homogenizer and preserved while being protected from light.
    Type: Grant

  • Process for production of amide compounds
    Patent number: 8889907
    Abstract: The present invention provides a method for producing an amide compound from a nitrile compound using a biocatalyst that realizes low cost, energy saving and low environmental burdens. The production method of the amide compound of the present invention is a method for producing an amide compound from a nitrile compound using a biocatalyst in a reactor, wherein the nitrile compound is reacted with the biocatalyst to produce the amide compound under such stirring conditions that the stirring power requirement is in the range of 0.08 to 0.7 kW/m3.
